GEORGE F. DUNN, OF BROCKTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TOWILLIAM B. ARNOLD, OF NORTH ABINGTON, MASSACHUSETTS.

VAIVIP THROATING AND MARKING MACHINE.

Application filed October 21, 1909.

To all whom it may concern Be it known that I, Gnonon F. DUNN, a citizenof the United States, and a resident of Brockton, in the county ofPlymouth and Commonwealth of Massachusetts, have invented an Improvementin Vamp Throating and Marking Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to dieing and marking machines and moreparticularly to machines for throating and marking the vamps of bootsand shoes, and among other objects provides means for accuratelypositioning Vamps beneath a throating die, and adjustable means formarking the vamps.

The character of the invention may be best understood by reference tothe following description of an illustrative embodiment thereof shown inthe accompanying drawings wherein:

Figure 1 is an end elevation of a vamp throating and marking machineembodying my invention; Fig. 2 is a side elevation of Fig. 1; Fig. 3 isa vertical section, taken on line 33 of Fig. 1; 1 is a plan of Fig. 1with the cutter die and its support removed; Fig. is a horizontalsection, taken on line 55 of Fig. 1; Fig. 6 is a horizontal sectiontaken on line 6-6 of Fig. 2; and Fig. 7 is a section taken on line 77 ofFig. 5.

The illustrative vamp throating and marking machine shown herein asembodying my invention comprises (Fig. 1) a die block 7, supported onthe usual table 9, rotative about the central post 10 (Fig. 4)projecting upwardly from the machine base 11. The upper periphery ofsaid table 9 is provided with a rack 12 adapted to cooperate with theusual devices, (not shown) for intermittently turning the table todistribute the wear on the surface of said block.

To cut the work on the die block a U- shaped throating cutter die 13(Figs. 2, 3, 5 and 6) is provided of flexible ribbon metal sharpened onits lower edge and is carried by frame 15, secured to a vertical post16, which may be vertically reciprocated in any suitable manner to causethe cutter Specification of Letters Patent.

Patented Nov. 17, 1914:.

Serial No. 523,902.

to descend at the proper times toward the die block to cut the workthereon. To adust the die to cut throats of various sizes the legs ofthe die may be mounted in carriers 17 and 18 (Figs. 3 and 6), havingrespectively upwardly projecting studs 19 and 20, extending throughdiverging elongated slots 21 (Fig. 5) in a horizontal plate 22 securedto and depending from the frame 15. These studs also extend throughelongated slots 23 in a sliding plate 24, superposed on the plate 22,the latter slots being substantially perpendicular to the median line ofthe cutter die, and cross the diverging slots 21 referred to. It will beapparent that by sliding the plate 24: on the plate 22 the studs 19 and20 and the cutter leg carriers 1? and 18 will be caused to approach orrecede from each other according to the direction in which the slidingplate 24 is moved. The curved end or bend 13 of the U-shaped cutter maybe positively adjusted to conform to the adjustment of the supports forthe legs of the cutter by a narrow, sliding end carrier 25 (Figs. 3 and6), guided between triangular shaped guides 25 (Fig. 6) secured to theunder face of said plate 22, the diverging edges 25 of said guides alsoconstituting guides for the incurved ends of the cutter leg carriers 17and 18. The carrier 25 has a depending projection 25 curved to conformto the curvature of the cutter, said cutter being received between saidprojection and the curved, depending end of a strip 26 screwed orotherwise secured to said sliding carrier 25. To move this carrier withthe plate 21 referred to, a stud 27 is secured to said carrier andprojects up through an elongated slot 28 (Fig. 3) in the plate 22 and issecured at its upper end to said plate 24. The plate 24. may be slid onthe plate 22'by means of a screw 36. having an end threaded into a lug37 extending vupwardly from the plate 2 1. The opposite end of saidscrew is journaled in a bearing in an upturned end 38 of the plate 22(Fig. 2), and is provided with a suitable handwhcel 39. The screw 36 iscapable of rotation in its bearing but is prevented from longitudinalmovement therein by suitable collars. As a result,

when the handwheel 39 is rotated the lug 37, with its plate 24, will beslid causing the cutter to expand or contract as desired. It will beapparent that as the leg supports approach, the, curved portion of thecutter will be shorter and the straight portion or legs of the cutterwill be proportionately longer.

To permit said legs to slide in their supports to conform to thenarrowing or widening of the curve or bend of the cutter they are notfixed to said supports but are adjustably supported in their carriers bypins 29 (Figs. 3 and 6) projecting through the legs of said cutter andreceived by elongated slots 29 in said carriers 17 and 18.

To prevent the vam as or the throat blanks cut from said Vamps frombeing pulled up from the die block with the cutter after the cut ismade, a stripper may be provided for said cutter. Herein a stripperplate 30 (Figs. 3 and 6) smaller than but of a shape similar to saidcutter is supported within the latter by guiding studs 31 received byhollowposts 32 depending from the plate The stripper plate 30 issupported by a central plunger 33 entered into a hole 33 in the platesaid hole being counterbored to receive a head 3% on said plunger. Thishead is normally seatedat the base of said counterbore by a spring 35encircling said plunger and compressed between the under face of theplate 22 and the stripper plate. hen the cutter descends to cut thethroats in the vamps the stripper shares in this descent until it comesin contact with the top vamp when its movement is arrested by itsengagement therewith. As the cutter continues downwardly to cut throughthe vamps the base of the counterbore withdraws from under the stud head3% and the spring 35 is compressed. WVhen the cutter ascends thestripper will press the Vamps down until after the cutter is'abovesaidVamps. The continued upward movement of the cutter will cause theplunger head 34 again to be seated on the base of said counterbore andthe stripper will be drawn up from engagement with the Vamps.

The downward movement of the frame 15 is utilized not only to cut thethroats in the Vamps but also to mark the latter for any desiredpurpose, as to indicate the position of the shoe tip on the vamp. Tothis end vertical marking pins l0 are provided (Figs. 1, 2, 3 and 5) andmay receive adjustment corresponding or conforming to the adjustment ofthe cutter die, by passing said pins through diverging elongated slotse1 (Figs. 5 and 6) in the plate 22 referred to and upwardly throughguide wings 42, each provided with elongated slots 43 we tendingsubstantially perpendicular to the cutter die median line, and crossingthe diverging slots 41. These pins may occupy stripper sleeves 45 theupper ends of which ed and slid in said cross slots as described theseheads 51 are yieldingly pressed by said springs into sliding engagementwith horizontal bridge bars 55 (Figs. 1, 2 and 5), which divergesimilarly to the slots l1 and are supported at their ends above theplate 22 by spacing sleeves 57, secured to said plate by suitable bolts59. When the cutter die descends to cut the vamps the stripper sleeves45 share this movement until they come into contact with the top Vamps,when they are arrested by their engagement therewith, the continueddownward movement of the cutter die causing the marking pins 40 todescend against the resistance of the springs 53 and project through thestripper sleeves andpenetrate or mark the Vamps. When the cutter die ismoved upwardly away from the Vamps the stripper sleeves will remain incontact with the surface of the top vamp and cause the Vamps to bestripped from the marking pins 40. By the time the marking pins havepassed above the lower ends of the stripper sleeves the stripper sleevecollars d7 will be engaged by the wings 42 and will continue upwardlywith the die.

The marking pins d0 hitherto have been adjusted simultaneously and inconformity with the cutter die adjustment as by connecting the markerguides directly to a nut 1 on the screw 36 thereby causing the markersto share directly the adjustment of the die. By my invention the markerguides may not only be adjusted in conformity with the cutter die tocorrespond tothe size of vamp throat cut, but a gage is provided forsaid markers whereby they may be given a preliminary adjustmentrelatively to said die, so that, among other things, when marking thepositions of shoe tips the distance from the vamp throat or die to theinner edge of the tip may be varied as desired. This gage comprises themarker guide wings 4:2 referred to which are secured to or form parts ofvertical guide plates 61 (Figs. 1 and 5), said plates being providedwith dovetailed projections 63, which are received by similarly shapedhorizontal grooves, in a nut 65, threaded on the cutter die adjustingscrew 36 at a point between the lug 31 and the bearing end 38. Theseopposed guide plates are connected by a bridge plate 67, the latterhaving a threaded opening receiving an adjusting screw 69 provided witha handwheel 70, said screw being journaled in an open bearing 71 in alug 73 projecting upwardly from the nut 65. The screw is capable ofrotation in said bearing but not of longitudinal movement relativethereto. When the die adjusting handwneel 39 is rota ed to vary theadjustment of the cutter die the nut will travel on the screw 36 causingthe marker guide wings $9. to share in this movement and be adjusted inconformity with the adjustment of the throating die for the sizedesired. By turning the handwheel of the preliminary adjustment screw69. the marking pin adjusting wings 4:2 may be slid relatively to andindependently of the nut 65 to vary the distance of the marking pinsfrom the curved end of the cutter die, furnishing several adjustmentsfor each adjustment of said die. This is found to be a very advantageousconstruc tion, since the length of the vamp between the throat and shoetip may be varied irrespective ot' the throat cutter adjustment. Theindependent marker adjustment is equally advantageous in marking pointsfor bluchers and other purposes as desired.

To accurately the marking pins in predetermined preliminary positions ofad justment the referred to (Fig. 5) includes indicating meanscomprising a graduated scale 77 on a plate '77 which is mounted in agroove in the top of one of the marker guide plates 61, said scale beingadapted to be read against an index pointer 78 (Fig. 5) secured to oneside of the adjusting screw lug 73. Said scale is herein divided intothree divisions, indicating marker adjustments for shoe widths 1 to 6,each line indicating two widths.

To accurately and simultaneously set the cutter die and markers intopredetermined positions of adjustment, indicating means are providedincluding a graduated scale 79 on a plate 79 1 and mounted in a groovein the top of the plate 22, said scale plate being herein dividedtransversely into widths from 1 to G, and longitudinally into sizesnumbering from 5 to 11, inclusive, for each of said widths. Said scalemay be read against an index edge 81 of one of the marking pin adjustingwings e2 which slides over said plate 79. In using the indicating meansshown herein the marker pins may be given a preliminary adjustmentrelatively to the throating die by turning the small hand-screw 70. Asillustrated herein the scale line 5 G is set in line with the indexpointer 78. After this preliminary adjustment is made the largehandwlieel 39 is turned to cause the cutter legs to approach or recedeto give the desired cutter ad ustment and to give the final adjustmentof the markers, bringing the wing reading index 81 in line with any ofthe sizes in either of the rows of size v figures indicated by widths 5and 6 on the margin of said scale plate 79. As illustrated herein theedge 81 is set in line with size S of width 5. If the preliminaryadjustment is on line 3et, the final adjustment may be on any of thesizes in either of the rows of size figures indicated by widths 3 and 4-on the margin of said scale plate 79. And if the preliminary adjustmentis on line 1 2, the final adjustment may be on any of the sizes ineither of the rows of size figures indicated by widths 1 and 2 on themargin of the scale plate 79. As a result the markers may be adjustedindependently of said die. As shown herein the distance between the dieand the markers in-- creases as the widths are changed from 56 to 1-2.

The styles of shoe caps or tips change from time to time and to provideindicating means of sufficient range to indicate any length of cap orany extent of vamp between the curved end of the vamp throat and theedge of the shoe cap the capacity of the scale 77 on the plate 77 may beincreased by sliding said scale plate in its groove. To accuratelyindicate the adjusted positions of the plate 77 the latter is providedwith what may be termed a style scale 77 which may be read against anindex line 77 on an edge portion of the top of one of the guides 61.Herein this scale is divided into divisions numbered from 1 to 4, butany number may be used as desired. The plate may be secured in itsadjusted positions by a set screw 77 entered through a slot 7 7.

In similar manner the range of the scale '79 may be increased by slidingthe scale plate 7 9 in its groove and its positions of adjustment may beindicated by a style scale 79 (Fig. 5) divided into divisions, hereinalso numbered from 1 to l, said divisions being adapted to be readagainst an index line 79 on said plate 79. This plate may be secured inits adjusted positions by a set screw 79 entered through a slot 7 9 insaid plate.

It will be apparent that when said plates and 79 are in the positionsshown inFig. 5 a number of indicated adjustments may be effected aspreviously described, but by sliding said plates and with reference tothe style scales 77 b and 79 a new set of adj ustments may be had by thescales 77 and 79' with each of the divisions of the style scales 77 and79 as a nucleus.

In using the machine a great many Vamps may be cut oil. one size, andthe machine may not need to be adjusted with much frequencv, but when itis desired to cut vamps of different sizes and with dilferent markings,the adjustments may be very easily and quickly made, by simply turningthe handwheels with reference to the indicating means, as described.

An important feature of my invention consists in providing means wherebyvamps may be accurately positioned on the die block beneath the cutter.To this end the supporting area of the block is supplemented by ahorizontal plate 83 (Figs. 1, 2, 3 and 4) detachably connected to thebase 11 by vertical studs 85 projecting downwardly from the plate 83 andhaving reduced ends 87 adapted to be received by hollow posts 89projecting upwardly from the base 11., The inner portion of this plateadjoins the die block 7 on a level therewith, and is shaped to conformto the peripheral contour thereof. The side edges of the plate 83 areprovided with guides 91 (Figs. i and 7) which extend beyond the plate 83and overlie the-die block 7 "for a substantial distance. Mounted toslide on said block is a vamp supporting tray 93, (Figs. 1, 4 and 7) ofsheet material and having side strips 94: secured thereon and adapted toslide in said guides 91. The tray has a U-shaped cut away portionsufiiciently large to permit the thro-ating die to pass through saidtray for any adjustment of said die. The inner end of this tray isprovided. with a transverse cleat or stop 97 (Figs. 3 and 4) herein ofangle iron secured thereto. One or more vamps may be accuratelypositioned on said tray 93 by long, curved guide fingers 99, 101,resting on the tray 93 and adapted to slide toward and from each otherto center and accurately position the vamps on the tray with their endsabutting against the stop 97. The guide fingers 99 and 101 may beadjusted toward and from each other by an oppositely threaded screw 103,rotative in, but incapable of longitudinal movement in a bearing box105, secured to the side of an upwardly extended end 107 secured to saidtray. To contribute to the guidance of the fingers '99, 10 1, theirscrew receiving ends 109 are enlarged and squared, to slide against theface of said end 107 and the adjacent surface of the tray 93. The screw103 may be turned to move said fingers toward or from each other by asuitable handwheel 111. Since the opposite outer edges of a vamp are notsymmetrical, the guide finger 99 is provided with a. curvaturesomewhatgreater than that of the finger 101. Vamps for right and left shoes maybe cut in a single operation my superposing some of the vamps with theirsmooth sides up and others with their rough sides up. To permit themarking pins to pass through the tray in any of their positions of adjustment, said tray is provided with oblique, elongated slots 113.

To accurately position the vamp-receiving tray beneath the cutter dieand into positions corresponding to the cutter die and markeradjustments, a stop 115 (Figs. 1,

to receive an adjusting screw 125.

2, 3 and is mounted on the sliding, ad.- justing plate 2 1 for thecutter. Herein this stop is in the form of a narrow strip secured ontosaid plate adjacent the screw lug 37. This strip extends horizontallyfrom said plate over and beyond the plate 22 and thence is bentvertically downwardly to bring an edge 117 of its depending end adjacentone of the tray guides 91 as well shown in Figs. 2 and 5. Cooperatingwith this stop is a tray positioning gage (Figs. 1, 2, 4L, -5 and 7-)secured to one of said side strips 9 1 (Fig. 7). This gage comprises ablock 121 hollowed out horizontally to receive a longitudinally slidingsleeve 123 which may be interiorly threaded The shank of this screw isrotative in a'bracket 127 (Fig. 2) secured to an end of said block andis prevented from longitudinal movement therein by collars 129. The gageis provided with indicating means comprising a scale 131, herein on thetop of the block 121 (Figsa and 5). Said scale may be divided intodivisions numbered to indicate adjustments for vamp sizes from 5 to 11.To indicate the positions of adjust ment of said sleeve the block 121 isslotted to receive a T-shaped index 133 secured to said sleeve andmovable therewith. The scale may be read against the edge 135 of saidindex.

In use, the tray is slid from beneath the cutter die out onto thesupporting plate 83. One or more vamps 136 (Fig. 3) are then placedonthe tray with their ends abutting against the stop 97. The handwheel111 is then turned to cause the fingers 99 and 101 to approach andaccurately center and maintain the vamps in their superposed positions.The cutter die and markers having been adjusted as described to cut, forexample, the proper throat in a vamp, size 8 width 5 (as shown) the traygage screw is turned to bring the index edge 135 in alinement with theline indicating size 8 on the scale 131. The tray is then slid in underthe cutter die 13 until the outer end of the index sleeve 123 abutsagainst the edge 117 of the depending stop 115 whereupon the vamps areaccurately positioned to receive the proper length of threat to conformto the size of the cutter adjustment. After the die has descended andcut the throats of the vamps the tray 93 may be slid out from beneaththe die until the curved portion of its U-shaped opening 95 projectsbeyond the outer edge of the tray support 83. A slight downward pressureon the throat blanks, remaining in the throat after the cutter iswithdrawn, will cause the ends of said blanks to project down throughthe opening 95, permitting them to be readily pulled therethrough.

It will be understood that my invention is not limited to the particularembodiment shown herein, but that various modifications may be madewithout departing from the spirit and scope of my invention.
